Students explore the concept of trig identities. In this trig identity lesson, students use Mathematica to graph trig identities. Students see the trig identities graphically and enforce the notion that two trig functions can be equivalent.

For this math worksheet, students read the examples for using the techniques of mathematical modeling. They draw the angles in order to simulate the reflection of light while using a concave mirror.

In this math worksheet, learners investigate inequalities using problems like: If x and y are randomly determined so that 1 < x < 3 and 4 < y < 7, then what is the probability that | x – y |< 4?

First graders explore completing experiments through the scientific method.

Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry lesson, 7th graders take measurements and record data. They create a graph and analyze results.

Here is a phenomenal lesson on place value to the thousands place.  Learners construct numbers and identify the value of each digit, investigate building numbers using craft sticks and paper plates, and complete other meaningful...
